With my recent migration of servers from my basement to Amazon cloud servers, I had to rework how my email filtering was setup.
One of the challenges was how to handle the numerous mailing lists I participate in. Especially since I’m the list administrator for many of them.
After a bit of research, and experimentation, I found a pretty good formula for handling the filtering.
For anyone who runs a mailing list and has gotten pummeled recently with a rash of subscription attempts, they may be coming from mailbait.info.
A while ago I blogged on how to block mailbait, but it appears they have changed their host.
Their new host is ‘themailbait.bitbucket.org’.
I suggest you update your web server configuration to block any referrer that references the word ‘mailbait’ in the URL.
Here’s my new httpd.conf entry to block mailbait…
SetEnvIf Referer mailbait mailbait
Deny from env=mailbait
